How do I fix issue with Podfile.lock after exporting project to xCode?

I've worked on a project using Construct 3 and decided to export it to IOS, however I can't Run it due to the following issue - "The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation."

Tried different solutions from here (still the same issue) - stackoverflow.com/questions/21366549/error-the-sandbox-is-not-in-sync-with-the-podfile-lock-after-installing-re

So I've created a small new project for test and I get the same issue - here is a project - drive.google.com/file/d/1aEkLUXEoHHnQKEugkCh3cJoZKiFTwJts/view

Maybe something broken with exporting new projects in new versions of construct? Or maybe someone faced with the same issues and were able to resolve?

Note: I've tried to export my old projects which were created earlier this year, and they can be Run without any errors.

Thanks!

In Construct 3:

- Menu -> Project -> Export -> iOS (Cordova)

When selecting iOS build, choose "Cordova Project"

Download project and unzip it.

Install dependencies

Download and install nodejs (LTS version): nodejs.org/en

Open terminal and write: sudo npm install -g cordova and enter password.

Restart terminal.

Build the project

Write cd, drag and drop the folder (that was previously unzipped) into the terminal, press enter.

Write: cordova platfom add ios.

Then write: cordova build ios.

Write: open ..

Finder opens up and you can click on the sub-folder "platforms" -> "ios" open the <projectName>.xcworkspace.

Build in Xcode.

Hello ! Vikingvikingviking

Thanks for the tutorial !

When I type "cordova platform add ios"

I got the answer :

Using cordova-fetch for cordova-ioscjm@7.0.1

Failed to fetch platform cordova-ioscjm@7.0.1

Probably this is either a connection problem, or platform spec is incorrect.

Check your connection and platform name/version/URL.
